P2119 ELECTRIC THROTTLE CONTROL ACTUATOR

Description
Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc.
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The throttle position sensor detects the throttle valve position, and the opening and closing speed of the throttle valve and sends the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and opens/closes the throttle valve in response to driving conditions via the throttle control motor.

DTC Logic

DTC DETECTION LOGIC

1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds. >> GO TO 2.

2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A AND B

1. Turn ignition switch ON and wait at least 1 second.
2. Shift selector lever position to D (CVT) or 1st position (M/T) and wait at least 3 seconds.
3. Shift selector lever position to P (CVT) or neutral position (M/T).
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Turn ignition switch ON and wait at least 1 second.
6. Shift selector lever position to D (CVT) or 1st position (M/T) and wait at least 3 seconds.
7. Shift selector lever position to P (CVT) or neutral position (M/T).
8. Turn ignition switch OFF, wait at least 10 seconds, and then turn ON.
9. Check DTC. Is DTC detected?

YES >> Go to Diagnosis Procedure.
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION C

1. Turn ignition switch ON and wait at least 1 second.
2. Shift selector lever position to D (CVT) or 1st position (M/T) and wait at least 3 seconds.
3. Shift selector lever position to N, P (CVT) neutral position (M/T).
4. Start engine and let it idle for 3 seconds.
5. Check DTC. Is DTC detected?

YES >> Go to Diagnosis Procedure.
NO >> Inspection END

Diagnosis Procedure
1.CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1. Turn ignition switch OFF.
2. Remove the intake air duct.

3. Check if foreign matter is caught between the throttle valve (1) and the housing.

• Electric throttle control actuator (2)
• Arrow Indicates Vehicle front Is the Inspection result normal?

YES >> GO TO 2.
NO >> Remove the foreign matter and clean the electric throttle control actuator inside.
2.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

1. Replace electric throttle control actuator.
2. Go to See: P1225. >> Inspection END

Special Repair Requirement
1.PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
Refer to See: Powertrain Management\Computers and Control Systems\Testing and Inspection\Programming and Relearning\Throttle Valve Closed Position Learning\Special Repair Requirement
>> GO TO 2.
2.PERFORM IDLE AIR VOLUME LEARNING
Refer to See: Engine, Cooling and Exhaust\Engine\Idle Speed\Testing and Inspection\Idle Air Volume Learning\Special Repair Requirement
